[0013] This utility model provides a smelting apparatus for expansion alloys with an anti-splash protection structure, which has the following beneficial effects:
[0014] 1. This utility model, by providing a protective cover assembly, wherein the explosion-proof cover and the docking ring seat are combined in a flange structure, can stably fix the protective cover assembly to the top of the docking ring seat and form a structural shield for the internal and external environment of the smelting kettle. This minimizes unnecessary splashing during the smelting of the expanding alloy inside the smelting kettle. The above-mentioned structure can minimize the occurrence of safety accidents and ensure the safe operation of the device. In addition, the structure of the exhaust hole provides good ventilation for the smelting kettle. Furthermore, the reinforcing ribs on the surface of the smelting kettle ensure the structural strength of the smelting kettle itself.

The hydraulic columns are connected to the docking seats via top support seats, and the sliding piles are connected to one side of the docking seats via connecting piles. When the hydraulic columns extend or retract vertically, they can drive the entire protective cover assembly to move vertically, while simultaneously pulling the sliding piles to slide synchronously along the surface of the guide columns. This facilitates the docking or separation of the smelting assembly and the protective cover assembly. The above structure ensures the ease of docking and assembly between the device structures, as well as the operational flexibility of the device structure. It also ensures good stability and avoids unnecessary safety issues. Furthermore, the detachability of each structure facilitates maintenance by operators. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] like Figures 1 to 5 As shown, a smelting apparatus for an expansion alloy with a splash-proof protective structure includes a frame 1 and a protective cover assembly 5. Stabilizing frames 2 are vertically installed at the four opposite corners of the top of the frame 1, and lifting columns 3 are vertically installed on both the left and right sides of the frame 1. A smelting assembly 4 is installed in the middle of the frame 1. The protective cover assembly 5 is installed on top of the smelting assembly 4. The protective cover assembly 5 includes an explosion-proof cover 501, an exhaust port 502, a connecting seat 503, and a docking seat 504. An exhaust port 502 is provided in the middle of the top of the explosion-proof cover 501, and connecting seats 503 are symmetrically arranged on the left and right sides of the explosion-proof cover 501. A docking seat 504 is also provided on the side of the explosion-proof cover 501. The smelting assembly 4 includes a smelting kettle 401, a docking ring seat 402, and reinforcing ribs 403. The top of the smelting kettle 401 is provided with... The docking ring seat 402 is provided with reinforcing ribs 403 on the side surface of the smelting kettle 401. One side of the support seat 303 is connected to the docking seat 504. The end of the connecting pile 205 away from the adjusting bolt 204 is connected to the connecting seat 503. The top surface structure of the interface 102 matches the bottom surface structure of the docking ring seat 402. The interface 102, the docking ring seat 402 and the explosion-proof cover 501 are connected by a flange structure. The explosion-proof cover 501 and the docking ring seat 402 have a flange structure combination, so that the protective cover assembly 5 can be stably fixed on the top of the docking ring seat 402 and form a structural shield for the internal and external environment of the smelting kettle 401, thereby avoiding unnecessary splashing during the smelting of the expansion alloy inside the smelting kettle 401 as much as possible.
[0024] like Figures 1 to 5As shown, the device frame 1 includes a frame body 101, a docking interface 102, and a fixing hole 103. The docking interface 102 is provided in the middle of the top of the frame body 101, and the fixing holes 103 are vertically provided at the left and right ends of the bottom of the frame body 101. The stabilizing frame 2 includes a fixing base 201, a guide post 202, a sliding pile 203, an adjusting bolt 204, and a connecting pile 205. The guide post 202 is vertically provided on the top of the fixing base 201, and the sliding pile 203 is connected to the surface of the guide post 202. The adjusting bolt 204 is horizontally installed on one side of the sliding pile 203, and the connecting pile 205 is horizontally installed on the side of the sliding pile 203 near the protective cover assembly 5. The guide post 202 vertically passes through the middle of the sliding pile 203, and the sliding pile 203 and the adjusting bolt 204 are threaded together. The fixed seat 201 and the guide column 202 are welded together, and the guide column 202 is movably installed at the top diagonal of the frame 101 through the fixed seat 201. The lifting column 3 includes a hydraulic column 301, a mounting seat 302 and a support seat 303. The bottom of the hydraulic column 301 is provided with the mounting seat 302, and the top of the hydraulic column 301 is provided with the support seat 303. The hydraulic column 301 is connected to the docking seat 504 through the top support seat 303, and the sliding pile 203 is connected to one side of the connecting seat 503 through the connecting pile 205. In this way, when the hydraulic column 301 extends and retracts in the vertical direction, it can drive the entire protective cover assembly 5 to make structural displacement in the vertical direction, and at the same time pull the sliding pile 203 to slide synchronously along the surface of the guide column 202.
[0025] In summary, as Figures 1 to 5 As shown, when the expansion alloy smelting device with anti-splash protection structure is used, the first thing to do is to connect the protective cover assembly 5 and the smelting assembly 4. The pneumatic lifting columns 3 located on both sides of the device frame 1 will be vertically extended and retracted by the hydraulic column 301 fixed to one side of the frame 101 by the mounting seat 302. This will drive the top support seat 303 to be raised and lowered synchronously, so that the protective cover assembly 5 connected to the side docking seat 504 of the explosion-proof cover 501 can be moved as a whole.
[0026] As the entire protective cover assembly 5 operates, the sliding pile 203 connected to one side of the connecting seat 503 by the connecting pile 205 will slide synchronously along the surface of the top guide post 202 of the fixed seat 201, thereby ensuring the stability of the movement of the protective cover assembly 5.
[0027] As the explosion-proof cover 501 connects with the docking ring seat 402 on the top of the smelting kettle 401, the two can be structurally fixed by using bolts as needed. At the same time, by turning the adjusting bolt 204 on one side of the sliding pile 203, the tightness of the connection between the guide column 202 and the sliding pile 203 can be adjusted to ensure the stability of the device structure and thus ensure the smooth operation inside the smelting kettle 401.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
